/ 1o all whom t may conce-rn Be it known that l, OWEN MARSHALL JONES, acitizen of the United States, and a resident of the borough ofManhattan, city, county, and State of New York, have 1nvented certainnew and useful Improvements in Valves, of which the following is aspecification, accompanied by drawings.

The invention relates to improvements in valves, Vbut in particular toimprovements in valves commonly known as pilot valves, which are used toadmit a-nd shut-off alternately the feed of fluid pressure employed toactuate a device or a part of a device, although the invention may beused in any connection in which it is found applicable.

The objects of the invention are to improve upon and increase theefliciency of pilot valves.

Other objects of the invention are to increase the durability of pilotvalves by ar ranging combinations of parts so that as many of the partsas possible will follow up their own wear, thereby minimizing thechances of the valves becoming leaky.

Further objects of the invention are to produce two pilot valves, or aduplex pilot valve, in one valve body.

rFhe single pilot valves and the duplex pilot valves having features ofconstruction, combinations of elements, and arrangement of parts, ashereinafter described and claimed in this specification, and shown inthe accompanying drawings, in which- Figure 1 is a side elevation,partly in section, of a horizontal single pilot valve.

Fig. 15 is an elevation of Fig. 14, showing the yoke that rotates thevalve stems.

It is to be noted that the` several valve seats in any one of the pilotvalves may be held permanently in place by various methods; therefore, Ido not show any details of the method for retaining them in place, anddo not limit myself to any specific method. Also, it is to be noted thatI do not limit myself to any special shapes of the ends of the severalstem sections for engaging the several sections of which the completedstem is composed, nor to any special number or shape of ports orapertures through the valves and the valve seats.

Referring to the drawings, in Fig. 1 l. have shown a single pilot valvewith its body in a horizontal plane and the stein and valves thereinrevolved by a fork vshaped lever'. 1 is a body or casing of the valve. 2is a head to cover the pressure end of the valve body. 3 is a head tocover the exhaust end of the valve body. 4 is a sectional stem whichrevolves the valves. 6 is the inlet to the inlet chamber. 5 is theoutlet for the exhaust from the exhaust chamber. 43 is a port thatconnects the combined outlet and inlet chamber 10 with the combinedoutlet and inlet 13 shown in elevation in Fig. 2. 19 is a passageconnecting the inlet chamber 8 and the inlet of the valve body. 2O is apassage connecting the exhaust chamber 12 with the exhaust outletof--the valve body. 14 is a pin for supporting one end of the forkshaped lever. 9 is the inlet valve seat, which may be an integral partof the valve body or a separate member suitably held in place in thevalve body, and may have at least one aperture through'it. 11 is theexhaust valve seat, which will be suitably held in place in the valvebody, and may have at least one aperture through it. 7 is a pin 0r lugattached to the head 2 to hold the valve S in position. 8 is a revolvingvalve with at least one aperture through it to correspond with the valveseat 9. 10 is a revolving valve with at least one aperture through it tocorrespond with the valve seat 11. 12 is a revolving disk which bearsagainst the end of the head 3 for preventing leakage around the valvestem and through Vthe valve headv 3. The two valves and the disk may berigidly mountedon the sectional stem or may be enlargements of the stem.placed between the outside surface of the head 3 and the collar 23, andis kept under tension to hold the disk 12 against the inner end surfaceof the head 3. 15 is a fork shaped lever with one end of it attached tothe section 35 of the sectional stem and the other end loosely placedover the pin 14, and is7 as shown, made of two sections bolted together.a is an offset end of one section of the lever. 16 represents the end ofthe means which operates the lever. 18 is a bolt for engaging 16 withthe lever. 35, 35; 34, 33 and 32 are sections comprising the sectionalstem. 35 may be attached to the face of the disk 12, 35 may be attachedto the back of the disk 12; 34 may be attached to the face of disk 10;33 may be attached to the back of 'l the disk 10, 32 may be attached tothe face of the disk 8. Or

the sections of the stem may be integral parts of the correspondingvalves and the disk. The stem as shown is with the several sections in adirect line7 and with the intermediate ends engaged so that there can bea sliding movement between the sections; in this manner the sectionsattached to the valve 10 can float longitudinally forward or backward asthere is a space between the ends of the flattened ends of the sectionsand the bottoms of the` grooves in the grooved ends of the sections;this permits cach valve to move independently of the other valve so asto follow up the wear on the faces of the valves or the wear on thefaces of the seats against which the valves seat. It is to be noted thatas the f-ace of the disk 12 or the inner faced end of the head 3 wearsthe stem section 35 will protrude farther through the head 3 and the end25 of the lever will travel with this stem section and the end 27 of thelever will slide on the pin 14 in the same direction and the bolt 18will slide through the end of part 16. By the construction of the leverabove described it is shown that the lever travels longitudinally withthe above mentioned wear of the disk 12 or the inner end of the head 3without putting a sidewise pressure on the part 16 and therebyeliminating extra friction in the movement of the lever. For conveniencethe lever is shown in the plan view while in actual operation the endsof the lever will be in a horizontal position as shown in Fig. 2. 28 isan aperture through the inlet valve 8. 29 is an aperture through theinlet valve seat 9. 30 is an aperture through the exhaust valve 10, 3lis an aper 22 is a spring ture through the exhaust valve seat 11. Theoperation of this form of valve is as follows: By referring to thedrawing it will be seen that the aperture through the exhaust valve isin register with the aperture through its seat, and the aperture throughthe inlet valve is out of register with the aperture through its seat.While the valves are in these positions there is no pressure in thechambers 10 and 12 as the fluid which creates the vpressure has beenexhausted through the exhaust valve and lexhaust chamber toatmosphere.Vv lVhen the valve stem is revolved the aperture in the inletvalve registers with the aperture in its seat and the exhaust aperturesare moved out of register; then the fluid under pressure passes throughthe inlet valve and enters into the chamber 10 and out through the port43 and the combined outlet andinlet 13 and to the device or part to beactuated.

` In Fig. 2, I have shown an end elevation of Fig. 1.V I have shown thelever 15 in its true position when it is ready for operation. 16 is ameans for operating the lever 15 and is moved upwardly and downwardly bythe beam 44, the beam 44 being actuated by suitable means.

In Figs. 6 and 7, I have shown a modification of Fig. 1 in so far as theform. and location of the inlet and the outlets7 and the means forrevolving the stem are concerned. I have also shown the valve in avertical position for operation. The passages 37 and 36 perform the samefunctions as the passages 19 and 20 respectively and all of the otherparts within the valve body are the same in form and operation andperform the saine functions as in Fig. 1.Y 40 is a yoke with two pins 41protruding from its inner sides. 33 is a spirally grooved rotativemember which is mounted on the section 35 of the stem and is heldrigidly in place by the set screw 39. 42 and 42 are lugs on the side ofthe valve body to act as guides for the yoke. The two pins 41 are forengaging the two grooves in the spirally grooved rotative member. 44 isa rod or beam which is suitably actuated and moves the 7oke u )ward anddownward the Vo oeraf in a direction the reverse of its lirst move-.

ment thereby reciprocally revolving the stem which revolves the valvesin a similar manner and for the same purposes as the two valves in Fig.1 are moved.

In Fig. 10, I have shown a type of damper regulator as one of theapplications of the pilot valve of the construction shown in Fig. 6 butl have not shov'vlfn'the pilot valve in Section as the description ofthe pilot valve in Fig. 1 and Fig. 6 isclear asto its functions andoperation which were explained in the description of Fig. 1 inconnect-ion with the damper regulator lshown inY Fig. 10. The damperregulator' is Oneapplication for the pilot valve. The damper regulatoris for opening and closing the damper in the smoke stack Vof a boilerwhen the steam pressure lowers or rises respectively. The steam isconnected from the boiler vto the chamber 45 through the pipe 46. Whenthe predetermined mean pressure obtains in the boiler the weight 47 onthe beam 44 holds down the diaphragm `b` and the beam holds down theyoke -40 of the pilot valve, when in that position theinlet valve in thepilot valve is closed. When the steam pres'- sure rises above thepredetermined mean pressure the diaphragm b raises V the beam 44whiclimoves up the yoke 40 of the pilot valve, the exhaust valve isclosed 'and the inlet valve is opened, the `water pressure whichoperates the piston 51 enters -through the inlet valve into'the cmbinedoutlet and inlet chamber and out through the opening 13 and passesthrough the pipe 48 and enters the chamber 49 rvand forces lthe piston51 upwardly andthe weight 58n the damper arm closes the damper. When thesteam pressure lowers to thepredetermined mean pressure the beam 44moves down to the position shown and closes the inletl valve in thepilot valve body and opens the exhaust valve thereby rreleasing thepressure under the piston 51 and the weights 53 mounted on the rod 52push the piston downwardly and by means of the rope or chain 54 pullsthe Idamper arm upwardly thereby again opening the damper.

Iu'Fig. 11, I have shown two ,pilot valves or a duplex pilot valve inone shell providing a valve *bodyv for 'casing for, each pilot valve.The center chamber 76 Shown inthe shell is the inlet chamber for bothpilot valves. A valve of this construction is suitable forlo-Jeratingtwo devices or for operating a piston in reciprocatingmotion. Fluid pressure is employed for operating Athe devices or thepistn and is centrolled by the pilot valve. 61 is the valve body orcasing. 62 is 'a head for covering the 'tp end of the valve body. 63 isa head for covering the bottom end ofthe valve body. 7 6,"is fthe inletchamber into which the fluid enters and serves both pilot valves asV theinlet chamber. 7 8 is a combined outlet and inlet chamber from which thefluid passes to a part to be actuated and into which the fluid entersfrom the part actuated to exhaust Ithe fluid. is an exhaust chamber into"which the fluid is exhausted `fr'ol'n'th'e ehamber 78. 74 'isI'ceiilbi'ed liut/let 'and inlet l"elzi'aiibe'r fromwhich the fluidpasses to a part to be actuated and into which the fluid enters from thepart actuated to exhaustdthe fluid. 72 is an exhaust chamber into whichthe fluid is exhausted from the chamber 74.` 73, 7 5, 78 and 80 arevalve seats which may have at least one aperture through them. 74 and 79are revolving exhaust valves with at least one aperture through each ofthem to register with the apertures in their corresponding seats. 76 and77 are revolving inlet valves which may have at least one aperturethrough them to register with the apertures through their correspondingseats. 64 is a revolving sectional stem. 64, 65, 66, 67, 68, 69, 70,70', and 71 are the sections of which the revolving stem consists. 38 isa spirally grooved rotative member which is held in place on the outerend of the stem, and this member is revolved by the pins on the innersides of a yoke such as is shown in, Fig. 7 and described in thedescription of Fig. 6, and is for revolving the stem. 72 is a disk whichseats on and revolves on the faced inside end of the head 62, and is to)revent the leaking of the fluid around the stem and through the head62. 22 is a spring lwith one of its ends bearing on the head 62 and theother end bearing against the ring 23, and is for holding the disk 72against the inside faced end of the head 62. 83 is an inlet foradmitting the fluid into the inlet chamber. 82 and 84 are each acombined outlet from and an inlet to the chambers 74 and 78respectively. 86 and 87 are passages to connect the exhaust chamberswith the passage 88 so that fluid from both exhaust chambers isexhausted through one exhaust outlet. is an outlet in the side of thevalve body through which the fluid is exhausted from the passage 88. 92is an aperture through the valve 87. 91 is an aperture through the seat78. is an aperture through the valve 79. 89 is an aperture through theseat 80. 93 is an aperture through the valve 76. 94 is an aperturethrough the seat 75. 95 is an aperture through the valve 74. 96 is anaperture through the seat 73. By the construction as shown it will .beclearly seen that the valve body contains two pilot valves with onepilot valve in the top half of the body and one pilot valve in thebottom half of the body, and both pilot valves being fed through acommon inlet chamber and having a common exhaust outlet, and beingoperated by one stem. The operation is as follows: In describing theoperation I will refer to Figs. 7, 10 and 13. It is to be noted that onepilot valve operates reversely of the other, as one is admitting fluidto the part to be actuated, the other is permitting the exhaust of thefluid and vice versa. For example, the duplex pilot valve vcan beapplied for eperating a piston in reciprocating movements such as thepiston 103in the cylinder 1 ()1 in Fig. 13, which maybe required foroperating a damper regulator, and thecylinder 101 is substituted lforthe 'cylinder c of Fig. 10 and weights are not mounted on the rod 104,the pilot valve being actuated by a yoke as shown in Figs. 7

and 10. The piston has finished its downward travel and the valve` stemhas been 'revolved, and, as shown in Fig. 11, the upper inlet valve hasbeen closed thereby cutting off the pressure inthe chamber 74', theupper exhaust valve has been opened, the lower` inlet valve has beenopened, and the lower exhaust valve has been closed. The Huid enteringthe inlet chamber through the inlet 83 will pass through the aperturesof the valve 77 and the seat 78 into the chamber 78 and out through theoutlet 84 and through the pipe 98 and the port 107 to the under side ofthe piston and will Vforce the piston up. The fluid on the top of thepiston will be pushed out of the chamber through the port 108V and thepipe 99 and the inlet 82 into the chamber 74 and out through theapertures of the valve 74 and the seat 7 3 into the exhaustv chamber 72and out through the passages 87 and 88 and the outlet 85 to atmosphere.When the piston reaches .the top of the cylinder the damper has beenclosed. When the steam pressure inY the boiler falls back to thepredetermined mean pressure then the beam 44 lowers and pulls down theyoke 4() and the valve stem is reversely revolved and the valves of thepilot valves are revolved so that the apertures through the severalvalves are in reverse positions of those shown in Fig. 11. This willplace the apertures of the inlet valve 77 and the seat 78 out ofregister thereby closing the valve 77 and cutting oil fluid pressurefrom the chamber 78, and will place the apertures of the exhaust valve79 and the seat 8O in register thereby relieving the pressure under thepiston, and will place the apertures of the exhaust valve 74 and theseat 73 out of register and the apertures of the inlet valve 76 and theseat 75 in register. Then the fluid from the inlet chamber' will passinto the chamber 74 and out through the outlet 82 and then pass throughthe pipe 99 and the port 108 to the top side of the piston and willforce the piston downwardly. Then the -fluid under the piston will 'bepushed out through the port 107 and through the pipe 9S and the inlet 84to the chamber 78 and through the apertures of the exhaust valve 79 andthe sea 80 into theV exhaust chamber and out through the passages 86 and88 and the outlet 85 to atmosphere. When the piston reaches the bottomof the cylinder then the damper is open again.

In Fig. 14, I have shown a modification of Fig. 11, in so Vfar that invthis ligure I have used two 'revolving valve stems one of them forrevolving lthe inlet valve and the exhaust valve of ythe upper pilotvalve., and the other stem for revolving theinlet valve and the exhaustvalve of the lower pilot valve. Also 7 0 l have shown a spirally groovedrotative member mounted on the protruding end of each of Ithe two stemsrorv revolving the stems. v With the exception of the stems, the valvebody and all the other parts are the same, are for the same functions,perform the same "functions, and operate the'same, as the similar-partsin Fig. 11. Asthe two stems can-'be revolved in the same direction theyare anequivalent in operation of the stems in Fig. 11. K "j In Fig. 15,I have shown a side elevation of Fig..14 with the yoke yfor revolvingkthe two spirali-y grooved rotative members.l 41 and 41a are p insforengaging the grooves 85' e and f in therupper rotative member, 41" and41c are pins for engaging the groves e and j" in the lower rotativemember. As Vthe grooves in both of the rotative members can be made tobe spiral in the same direction, 90 therefore the two members can berevolved simultaneously in the same direction, when thegyeke travelsupwardly or downwardly as the yoke is lactuated by suitable means. Thegrooves in one of the rotative members can be'made spiral. in ardirection opposite to the direction' of the spiral in the other member,thereby making it possible for the two rotative members to be revolvedin opposite directions.

Obviously, some features, partsor Lconstructions may be used withoutothers, and in combination with others, or may be embodied inwidelyvarying forms.
